Abstract (en)

A voltage conversion device includes first to fourth input-side switching elements provided on an input side of a smoothing inductance, first and second power supply lines provided on an output side of the smoothing inductance and configured to respectively supply power to a first load and a second load operating at an operating voltage lower than that of the first load; first and second output-side switching elements respectively provided on the first and second power supply lines, and a control unit configured to perform on/off control on the first and second output-side switching elements. The control unit turns on the first output-side switching element to supply power to the first load, without supplying power to the second load by turning off the second output-side switching element, during a period in which the current is supplied to the smoothing inductance by switching of the input-side switching elements.
